Lantana plant named ‘PIIL-CHW’

ABSTRACT

A new and distinct cultivar of  Lantana  plant named ‘PIIL-CHW’, characterized by its low growing, layered and spreading growth habit; leathery, scabrous dark green foliage; continuous flowering; and pale yellow flower buds that open to medium yellow with a darker yellow-orange center and age to white with a medium yellow center.

Genus and species of plant claimed: Lantana camara.

Variety denomination: ‘PIIL-CHW’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lantana plant, botanically known as Lantana camara, and hereinafter referred to by the cultivar name ‘PIIL-CHW’.

The new Lantana plant originated as a naturally occurring, non-induced branch mutation on a plant of Lantana camara ‘Chapel Hill Yellow’ (U.S. Plant Pat. No. 19,548). The cultivar ‘PIIL-CHW’ originated and was discovered in a cultivated environment in a greenhouse in York, S.C.

Asexual reproduction of the new cultivar by stem cuttings in Watkinsville, Ga. has shown that all the unique features of this new Lantana, as herein described, are stable and reproduced true-to-type through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

Plants of the new cultivar ‘PIIL-CHW’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with changes in light, temperature, soil and rainfall without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘PIIL-CHW’. These characteristics in combination distinguish ‘PIIL-CHW’ as a new and distinct cultivar.

-   -   1. Low growing, layered and spreading growth habit;     -   2. Leathery, scabrous dark green foliage;     -   3. Continuous flowering; and     -   4. Pale yellow flower buds that open to medium yellow with a         darker yellow-orange center and age to white with a medium         yellow center.

There are no other cultivars of Lantana with this combination of characteristics known to the inventor.

Plants of the new Lantana ‘PIIL-CHW’ differ from plants of the parent, ‘Chapel Hill Yellow’, primarily in flower color, as plants of ‘Chapel Hill Yellow’ have pale yellow flower buds that open to medium yellow with a darker yellow-orange center and do not change color as they age, whereas plants of ‘PIIL-CHW’ have pale yellow flower buds that open to medium yellow with a darker yellow-orange center and age to white with a medium yellow center.

Plants of the new Lantana ‘PIIL-CHW’ can be compared to plants of Lantana ‘Sunny Side Up’ (U.S. Plant Pat. No. 23,650). However, in side-by-side comparisons conducted in Watkinsville, Ga., plants of ‘PIIL-CHW’ differed from plants of ‘Sunny Side Up’ primarily in flower color, as plants of ‘PIIL-CHW’ have pale yellow flower buds that open to medium yellow with a darker yellow-orange center and age to white with a medium yellow center, whereas plants of ‘Sunny Side Up’ have yellow flower buds that open to yellow with a darker golden-yellow center and age to white with a yellow center.

Plants of the new Lantana ‘PIIL-CHW’ can be compared to plants of Lantana ‘LCBCW’ (not patented). However, in side-by-side comparisons conducted in Watkinsville, Ga., plants of ‘PIIL-CHW’ differed from plants of ‘LCBCW’ in the following ways. Plants of ‘PIIL-CHW’ had darker green, thicker, more scabrous foliage than plants of ‘LCBCW’. Plants of ‘PIIL-CHW’ had brighter flower color and larger flowers than plants of ‘LCBCW’. Plants of ‘PIIL-CHW’ had an overall larger growth habit than plants of ‘LCBCW’.
